Does anybody know of a chemical type cleaner for cleaning heavily
tarnished brass? The item is a complex moulding and very hard to clean
with cloth and brasso which just reaches the more exposed surfaces.

Diet Coke.

I heard that this was good too. I had been trying to clean a similar
intricate statue and tried it with coke. Having a large ultrasonic
cleaning bath that I had tried with various cleaning fluids before I
put 5 litres of coke in, plus the statue and turned it on.

What happens when you VERY rapidly shake 5l of coke? It was most
impressive, Dr Who special effects would have been proud of it.

Say after me "I'm a pillock" for some reason it had never crossed my
mind, gave SWMBO some amusement though so all was not in vain.
